My bad. I should have labeled thread "non-booter."
By not take a charge I was referencing the internal 3.6v battery must have gone
dead in storage and would not take a charge.
I did get it going. I used POWER CONT command and I'm letting it run today
while at work.
But something intermittent is going on. I need to assess behavior some more.
As Arnold said, I'll be back.

Just a thought here - many (most?) rechargeable AA size (and AAA size)
batteries are lower voltage than standard alkaline batteries.
An alkaline 1.5 volt AA can be replaced with a rechargeable AA, but the
rechargeable is usually labeled 1.2 volts. They're the same physical size, but
supply different voltages.
Thus, alkaline 4x1.5 volts = 6 volts. But rechargeable 4x1.2 volts = 4.8 volts.

Subject: Re: [M100] Non-charger Sometimes a cold boot can help after a NiCd
battery replacement. Then check the Vdd and Vee voltages are +5V and –5V
respectively. The voltage on the battery should be about 3.7V if it is
charging OK. It could be powering on just the screen is dim. Try powering
on, hit return (this takes you to BASIC) and then type BEEP and return. There
should be a beep if the unit is powering up but the screen is not working. If
the screen is dim the –5V (Vee) might be really low. The memory protect switch
is set correctly? I routinely forget to set this switch correctly when I take
a machine out of storage :( From: M100 <[email protected]> on

I took a Model T out of storage and it was completely dead and would not take a
charge.
I figured I'd use the opportunity to replace internal battery anyway.Installed
the new battery and it started right up, albeit with a Low Battery light. So I
assumed it just needed an overnight charge and would be as good as new. Just
got home from work and it is dead as a doorknob again after being plugged into
wall wort. I can solder and have a digital multimeter. Some clues on what to
check? I assume it is not charging.
